Arahan pengoptimuman

Arah pengoptimuman utama untuk strategi ini adalah:

  1. Mengoptimumkan tetapan parameter. Mengoptimumkan parameter seperti panjang dan kelancaran konstanta RSI Stochastic melalui pengujian balik yang luas.

  4. Sesuaikan saiz kedudukan berdasarkan analisis jangka masa yang lebih tinggi. Sesuaikan saiz kedudukan setiap perdagangan secara dinamik berdasarkan hasil analisis trend dari jangka masa yang lebih tinggi.
